The anti-skid (stabilitrak) system may have an incorrect calibration, which can cause the system not to properly detect a sensor malfunction. A malfunctioning sensor may cause the stabilitrak (ESC) to falsely activate, resulting in sudden changes in vehicle handling and deceleration. These unexpected changes in vehicle handling may cause a loss of vehicle control. Dealers will update the electronic brake control module (EBCM) software to correct this concern. The General Motors recall number is 11222.
The HVAC system may stop functioning due to a software issue in the climate control module. System failure would reduce the driver's ability to command the defrost function. This can reduce visibility, increasing the risk of a crash. To correct the problem, dealers will reprogram the electronic control module for the HVAC. The recall is expected to begin by March 11, 2011. The General Motors recall number is 11057.
General Motors is recalling 2010–2011 DTS and Buick Lucerne models with V8 engines due to contact between the starter/alternator cable and the power steering return line. This can result in a worn power steering return line, which can cause a power steering leak, possibly resulting in a loss of power steering. This can lead to an increase in the risk of a crash and/or an engine compartment fire. Dealers will secure or reroute the necessary lines, free of charge.
When moving the seats from a flat to upright position, the second row seat belt buckle may bind on the second row seat trim shield. This could prevent proper operation and securing of the safety belt, which would increase the risk of injury to an occupant. Dealers will modify the second row seat trim shields. The GM recall number is N100243. This recall began on August 18, 2010.
The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
The shifter cable adjustment may become dislodged. This may cause the vehicle to show that it is in "Park," when it could actually be in another gear. If this happens, the vehicle may move and not be secure. Dealers will inspect the shift cable adjustment clip to make sure it is fully engaged, and will replace any shift cables that cannot be secured. The General Motors recall number is 09041. The recall began on March 24, 2009.
The seat belt buckles in the second or third row seats may be missing a rivet. If a crash occurs, the buckle may separate from the strap, increasing the risk of injury to the passenger. Dealers will inspect the seat belt buckles and replace any as needed.
If a buildup of snow were to occur on the windshield, the movement of the wipers may be restricted. This could result in the wiper linkage becoming detached from the wiper motor, rendering the wipers inoperable. Visibility could be reduced, increasing the risk of a crash. Dealers will install a new wiper crank arm, driver's side link, and crank arm nut to correct this problem. This recall is expected to begin on October 13, 2008. The General Motors recall number is 08091.
The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.
